Description

  The present invention relates to a structure in which an opening / closing operation switch is attached to an outside handle, in which the door is locked and unlocked electrically by operating an opening / closing operation switch attached to the outside handle of the door.

Conventionally, a technique for electrically locking and unlocking a door lock provided on a door of a vehicle is known, and this electric locking and unlocking is a push button type provided on an outer surface of the door. A technique performed by operating an opening / closing operation switch is also known (see, for example, Patent Document 1).
There is also known a technique in which a hole is not formed in the door outer panel by assembling the opening / closing operation switch in advance to the outside handle of the door.

In the structure where the push button type opening / closing operation switch is attached to the outside handle as described above, the push button portion of the opening / closing operation switch is in the button through hole provided on the outer surface of the outside handle, and the outer peripheral clearance is constant. Position the sub-assembly so that it penetrates, and open and close the outside handle from the front side of the door outer panel so that the outside handle is partly inserted into the work hole provided in the door outer panel. Each operation switch is attached.
JP 2002-175736 A (FIG. 2)

However, when the outside handle is made small, if the opening / closing operation switch is subassembled when the outside handle is attached from the front side of the door outer panel, the part through which the opening / closing operation switch passes is outside the work hole. There are cases where it cannot be covered with the handle.
Therefore, in such a case, after setting the outside handle on the outer panel, it is conceivable that an opening / closing operation switch is retrofitted from the back side of the door outer panel using the mounting bolt of the outside handle.
In this case, when the open / close operation switch is fastened with bolts and nuts to be mounted without a positioning jig from the back side of the door outer panel, the fastening torque is input to the open / close operation switch, and the open / close operation switch is moved to the outside handle. May rotate from the normal position. As described above, when the opening / closing operation switch is rotated with respect to the outside handle, the push button portion penetrating the button through hole formed in the outside handle is displaced from the normal position with respect to the button through hole. The gap between the outer periphery of the button and the inner periphery of the button through-hole is not constant, causing problems that the appearance quality deteriorates, or the outer periphery of the push button part touches the inner periphery of the button through-hole and moves As a result, the operability may deteriorate.
Although it is possible to position the open / close operation switch by providing a locate pin or holding claw on the back side of the outside handle, the bolt and nut are usually fastened at a position offset from the push button position. In this case, it is difficult to provide an accuracy sufficient to stop the opening / closing operation switch from slightly rotating by the torque at that time, and it is difficult to solve the above-mentioned appearance quality problem and operability problem.

  The present invention is made by paying attention to the above-mentioned conventional problems, and even when an open / close operation switch is retrofitted to the outside handle, the push button is excellent in appearance quality and operability. It is an object of the present invention to provide an opening / closing operation switch mounting structure to which a part can be mounted.

In order to achieve the above object, an invention according to claim 1 of the present application provides an outside handle on the outside of a vehicle door, and a signal for locking and unlocking the door lock device on the back of the outside handle. The opening / closing operation switch is fixed with bolts and nuts, and this opening / closing operation switch is exposed to the outside through the button through-hole formed through the outside handle and is displaced by receiving physical input from the outside of the vehicle. In an open / close operation switch mounting structure comprising a push button portion to be fixed and a switch body fixed to the back side of the outside handle and forming an electrical signal based on displacement of the push button portion,
A mounting hole and a work hole are opened in the door outer panel of the door, and the opening / closing operation switch is located in the work hole,
A button through hole is formed in the outside handle, and a mounting bolt is erected on the back surface of the outside handle in the vehicle interior direction, and a locating pin is located near the button through hole. Standing in the direction of the car,
The push button part is attached through a button push hole of the outside handle and a first push button part supported by the switch body so as to be able to be displaced by receiving physical input from the input face, and transmitting on the back side. When the second push button portion is pressed with the second push button portion disposed so that the surface is in contact with or close to the input surface of the first push button portion, the first push button portion is displaced with respect to the switch body. Configured to
The switch body is formed with a protrusion and a screw insertion hole,
A mounting bracket for mounting the switch body is provided, and in the mounting bracket, a bolt insertion hole through which the mounting bolt is inserted, a screw hole through which a screw for fixing the switch body is inserted, and the locating pin are inserted into the mounting bracket. A locate hole for positioning with respect to the outside handle and an engagement hole into which the projection of the switch body is inserted are formed.
With the switch body inserted into the engagement hole formed in the mounting bracket, the screw inserted through the screw insertion hole of the switch body is screwed into the screw hole of the mounting bracket. And fixed to the mounting bracket,
A mounting bolt standing on the back surface of the outside handle is inserted into a bolt insertion hole of the mounting bracket and a mounting hole of the door outer panel, and a nut is fastened from the back side to fasten the mounting bracket to the door outer panel. And the switch body is fixed to the door outer panel,
The switch body and the outside handle sandwich the periphery on the back side of the second push button portion.

In the present invention, only the second push button part of the opening / closing operation switch is attached in advance to the button through hole of the outside handle. Therefore, even if the work hole formed in the outside handle and the door outer panel is formed in a small size so that the opening / closing operation switch cannot be secured in the work hole of the door outer panel, the opening / closing operation switch can be attached to the outside handle. .
After setting the outside handle to the door outer panel in this way, the switch body is attached to the outside handle with bolts and nuts. In this attached state, the input of the first push button portion supported by the switch body The surface is in contact with or close to the transmission surface on the back surface of the second push button portion.
Thus, since the first push button portion and the second push button portion are in contact with or close to each other, when the switch body is attached to the outside handle with the bolt and nut, the position of the switch body is determined by the fastening torque. If the outside handle is deviated from the normal position, the position of the first push button is only slightly shifted relative to the second push button attached to the outside handle. 2 The push button part is kept in a fixed state with respect to the outside handle, the relationship between the outer periphery of the second push button part and the inner periphery of the button through hole of the outside handle is kept constant, and the amount of gap changes As a result, the appearance quality is not deteriorated, and the operability is not deteriorated by being touched.
In addition, when the switch body is fixed to the outside handle, the back of the second push button is sandwiched between the back of the outside handle and the switch body, so the second push button is firmly fixed to the outside handle. Is done.
In the opening / closing operation switch that has been mounted as described above, when the second push button portion exposed from the button through hole of the outside handle is pushed from the outside of the vehicle, the transmission surface on the back surface of the second push button portion Is displaced in the vehicle interior direction and presses the input surface of the first push button portion, whereby the first push button portion is pushed into the switch body, and an electrical signal is formed in the switch body.

As described above, in the present invention, when the switch body is fastened to the outside handle with bolts and nuts afterward, even if the switch body is rotated from the normal position with respect to the outside handle by the fastening torque. The second push button part that penetrates the outside handle is kept in a fixed mounting state with respect to the outside handle without rotating, and can maintain a good appearance quality and can be operated with a single contact. The effect that the property does not deteriorate is obtained.
Moreover, since the back surface of the second push button portion is sandwiched between the back surface of the outside handle and the switch body, the second push button portion is firmly fixed to the outside handle, and the operability can be kept good. Thus, an effect that it is possible to prevent a mounting failure due to aged deterioration can be obtained.
